In this episode of the Waterpolo Expert Talk, Spanish national team goalkeeper Unai Aguirre gives a deep and personal insight into the reasons behind the long-term success of Spanish water polo and why Spain has become one of the most dominant nations in the world over the last years.

At only 20 years old, Unai is already part of the senior national team and one of the goalkeepers of CN Barceloneta, the most successful club in Spain. He расскаnts about his early years in Barcelona, how he started as a swimmer before switching to water polo at the age of ten, and why the goalkeeper position immediately felt natural to him – not only in water polo, but also in football. For Unai, being a goalie means having direct responsibility for the result, being part of the defensive heart of the team and always pushing himself to the highest level.

A central theme of this episode is the Spanish youth development system. Unai explains how young players from all over the country come together in national training centers where school and elite water polo are perfectly connected. This system allows Spain to constantly produce highly educated, mentally strong and tactically intelligent players. According to Unai, this is one of the main reasons why Spain has such a small gap between U18, U20 and senior national teams.

He also talks about the enormous impact of national team head coach David Martin, who is known for trusting young players and giving talents real opportunities at the highest level. This culture of trust creates confidence, responsibility and huge motivation among the next generation and allows players to grow quickly into international top performers.

Unai shares his personal experience at CN Barceloneta, where he recently extended his contract for another three years. He describes the club as a professional, family-driven environment with perfect conditions for development, where pressure is replaced by trust and daily high-level work. Training every day with world-class players has shaped his mentality and expectations toward himself.

The episode also takes a critical look at the current situation of the Spanish league. While Barceloneta remains clearly on top, Unai speaks openly about financial challenges after the pandemic, the rising costs for clubs and the consequences this has for competition, player transfers and the long-term stability of certain teams. At the same time, he sees a positive trend as many young players are now getting more playing time at the highest national level.

This episode offers a rare inside view into the Spanish high-performance system, the mentality of young top players, and the cultural foundations that have turned Spain into a global powerhouse in modern water polo.
